ApplicationV led December 6,11928. Serial No. 324,280.

rihis invention relates'to improvements in heatingattachments for ygas stoves andthe like.

The primary object of this invention is Y the ,p provision of an improved attachment adapted to be used with gas stoves and the like, by means of which a-'plurality ofV vessels l vor utensils may lbereadily heated from the heat produced by a single gas burner r the like, for the purpose 'of economically utilizlnqthe maximum amount of heat for cooking.

A` further provisionof an improvedvheater attachment for -gasranges and the like, which includes ,improvedimeans for directly heating a utensil above a gask burner andk laterally deflectingy the heat in a novel relation to another location where .an auxiliary vessel is placed.

" ing improvedv means ,vessels of various sizes.

f .f Other objects and advantagesof this invention will be apparent during thelcourse 4l [A further and important objectl of this inventionv is the `'provision of anv improvedr heater attachmentfor gas ranges, embodyof the following detailed description.V l f In the accompanying drawings, forming a- Y. part of this specification, and wherein' sim-- ilarreference characters designate corre-- sponding views.'

parts throughout the several Figure V1 is a longitudinal sectional view taken through the kimproved attachment, L taken substantially on the line 1--1 o-f'rFigure'2. v y l .y Figure 2 is a plan ,View of the improved at- Y tachment.

lFigure 3 is a fragmentary perspective viewshowingcooperatingy lid'or cover details for supporting a pluralityof vessels of different 1 sizes upon an opening'of the attachment.

In the drawings, wherein Lfor the purpose of illustration is. shown only a preferred em- Y coniprisesa housing Bhaving means C fory bodiment, of the'inventiomthe letter-Akmay generally` designate the "attachment, which supportingthereon a plurality ofvessels or utensils of different sizes, directly over ,a

burneriD the device furthermore including object of this invention is the.v

for support against a' grate `E for receiving vessels of various sizes in an efcient relation for proper heating.

The housing B is of novel construction, including a top wall structure provided with vperipherally depending side and end walls 11 conforming to the shape thereof, and depending in a plane at right angles to the .top wall. The top wall 10 includes the wallportion A11 atone end thereof, which is provided with an opening v12` wherein the adjustable lid structure C detachably fits in a novel relation for supporting vessels or utensils of 'dilierent sizes.- The wall 11 is connected with a wall portion 13 forming part of the top wall 10 by means of a transverse sloping wall portion 15,'-which extends upwardlv from the the wall portion 13 in a plane above the wall portion 11. The wall portion 13 has the grate E yeither detachably or integrally disposed thereon as a part thereof. The depending walls 11 preferably follow the contour Vof the plane of the wall portion 11 in order to offset Y' top wall, preferably in the form of the jnui meral v8,"and below the top wall a compa-rtment isprovided. A bottom wall 16 is disy compartment below the wall portion 11, and

after heating the vessel,1suchas shown at F supported thereon, the residue heat passes into the housing between the wall portion 13 and the bottom wallf16, for heating the vessel or utensil H supported on the'grate E.

Referring to 'theV cover struct-ure C, they same includes outer and inner ring-shapedv sections30 and 31 respectively. The wall 11 of the `lhousing B'isprovided with an under flange33 about the opening- 12, below the `plane of the top surface of the wall, adapted yto marginally support the ring-shaped cover section V 30. AVThis ringshaped c over'section has. an opening Sethereinwhich is 'eccentrically' positioned therein with respecttov the radius. from ywhich the outer circumference ofthersectiono Vis formech Onjthe under surface of the cover section V130 is disposed a dellecting flange 3,6, best shown 'in Figures l and 2' i of the drawing, butv also shown in Figure 3, which is segmental inform', and ex Vtends about the opening 345of thesection 30,y v'preferably concentrie-,therewith, for'islightly over 1809, andhas the lends 3 7 and 38 rela-M'v vtively kspaced andv extending in the direction;

of the ofi'setportion 15 ofthe top wall of the@ housing. The purpose of the flange 36 Vis to maintain the heat from'thel burner D vabout u the opening 34, and to deflect the lsarne there# from laterally into the space below 'the grate E forheating the auxiliary'utensilI-L- In or- "this Iposition;1t 1s preferred to provide Yav der'fthat the section SOwill alwaysassume notch @or opening A39 inthe .supporting flange 3?), whe'reinla dependingflug 4-0 on the-bottom oftheV lidolr cover section v30 isadaptedfto seat`,in the v relation shown inthe drawings,`

Y On these ribsv 67 the utensili-l isf adapted to seat, and, of course, the utensil will be spaced slightly above the wall portion CTV lto permit ofv a circulation of the heatalong thexhousingfB longitudinally thereof, duetov Y the l,fact Vthat these lribs prevent the utensil or ,S0 l vessel from seatingin a closed relation over l the opening upon which V theV grate E `is Ydis-Y posed.l Theconvergency of the ribs' 67 per#k f mits the vessel H toV be accurately"heatedv in j event Yit isless in dia-meter than the outer cir-v cumferen'ce of the deflecting flange'O.V
